Who is she?

Jean Piaget - a cognitive theorist suggested that language development is due to a wider development in cognitive ability and that a child cannot articulate ides or concepts that they are uanble to understand. Piaget argued that if a child needs to understand a concept such as the past, to be able to use language terms to refer to it. Also the concept of seriation ( the ability to place items in a series, such as ascending or decending orders) needs to be understood before a child could learn to use superlatives and comparatives. Object permenance features in this idea too. The idea that the object still exists even if it is not visible needs to be understood too, so that the child comprehends that everything has it's own separate identity and will still exist even when the child cannot see it.
